The AC load switch with a voltage up to 10 kV WT (hereinafter referred to as the switch) is designed to operate in AC networks with industrial frequencies of 50 and 60 Hz, with a rated voltage of 10 kV, and the frame is made of metal. It has 6 insulators. They are located at the bottom of the frame and are equipped with cutters. The insulators help to establish and break contacts. This switch is equipped with a chamber with special inserts. The WT-D-10/630A model is used for the circuit part. It helps to open and close them.
This product is also used for safe work in remote areas.
It is mainly used in the WT-L-10/630A2 in switch cabinets.
Conditions of use:
1.The altitude must not be higher than 1000 meters;
2.The humidity must not be higher than 80%;
3.The temperature ranges from -45°C to +40°C;
4.The position must be vertical.
